2024-07-04 21:07:13.900 -04:00 [ERR] User has been disabled

The test users are configured in Config.cs like so:

public static List<TestUser> GetUsers()
{
    return new List<TestUser>
    {
        new TestUser
        {
            SubjectId = "1",
            Username = "alice",
            Password = "password"

        },
        new TestUser
        {
            SubjectId = "2",
            Username = "bob",
            Password = "password"
        }
    };
}

I’ve stepped through the code and everything looks alright. The validator returns successfully and the client is setup correctly. Why is the log saying the user is disabled? The test users are setup to be active by default and I’m not seeing where in the call stack that the test user could be getting set to disabled. Can anyone point something out here?
